I have a simple text file, wich contains lines in tree hierarchy.
I have already registered it's extenstion, to bring up my custom
EditorPart, which builds an SWT tree based on the information of the text
file.

So far so good, but what i really want to achive, is when these text files
are updated outside the filesystem, i want my open editors to automaticaly
(and silently) notice the changes, and reload the editor with the updated
content.
